Bone Marrow Aspiration and Biopsy

Bone marrow is soft tissue in bones that assist in the development of blood cells. A bone marrow aspiration takes out a small amount of tissue in a liquid form for analysis. A bone marrow aspiration is different from a bone marrow biopsy. A bone marrow biopsy takes out actual marrow rather than a liquid form. In an aspiration, bone marrow fluid is suctioned out after a needle is inserted into the breast or pelvic bone. These tests are performed if there are unusual numbers or types of red or white blood cells or platelets. These tests can help to detect infections, anemia, leukemia or other blood disorders and cancers.
